Abstract
An apparatus includes a power converter and a controller. The power converter converts a received input voltage into an output voltage that powers a dynamic load. The controller controls a setting of a switching frequency applied to the power converter. During one operational mode, the controller transitions a setting of the switching frequency of the power converter from a first clock frequency signal to a second clock frequency signal depending on occurrence of phase alignment of the second clock frequency signal and the first clock frequency signal, which may eventually occur over multiple switching control cycles. Transition of the switching frequency from the first clock frequency signal to the second clock frequency signal at or around a time of the phase alignment reduces possible perturbations in the output voltage as a result of the clock frequency switchover.
